Fertilizer for treating farmland soil hardening and fertilizing method

Abstract

The invention discloses a fertilizer for treating farmland soil hardening and a fertilization method, and relates to the technical field of compound fertilizers, the fertilizer comprises the following components by mass percentage: 10-13% of nitrogen, 5-7% of phosphorus pentoxide, 6-8% of potassium oxide, 15-20% of active silicon, 55-65% of organic matter, and 4-8% of fulvic acid, the fertilization method comprises the following steps: applying the fertilizer before cultivation, and applying the fertilizer every 15-20 hours. Dicarboxylic acid is one or a combination of more of azelaic acid, sebacic anhydride, terephthalic acid and dimethyl terephthalate, and the use amount ratio of the dicarboxylic acid to the additional fertilizer is 1-2 L / 100 kg. By means of the method, farmland soil hardening can be effectively treated, meanwhile, nitrogen, phosphorus, potassium and organic matter can be provided for soil at the same time, and the soil quality is improved. The soil fertilizer efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a fertilizer for treating soil compaction in farmland and a fertilizing method. Background technique [0002] Due to the over-planting of cultivated land and the abuse of chemical fertilizers and pesticides, the beneficial original microorganisms in the soil accumulate a large amount of inorganic salts, which destroys the aggregate structure of the soil and makes the soil tend to be compacted and desertified. The usual treatment methods are direct application of organic fertilizers or livestock. Poultry manure, these fertilizers can also play a certain role in improvement, but in this process, from the collection, transportation, fermentation treatment, storage and transportation of livestock manure to the soil of the cultivated land, it is dispersed in the soil of the cultivated land, and it is subject to the metabolic expansion of the mold for many times. It produc...

[0002] Due to the excessive cultivation of cultivated land and the abuse of chemical fertilizers and pesticides, the beneficial original microorganisms in the soil accumulate a large amount of inorganic salts, destroying the aggregate structure of the soil and making the soil tend to compact and desertify. The usual treatment method is to directly apply organic fertilizer or livestock Poultry manure, these fertilizers can also play a certain role in improvement, but in the process of collecting, transporting, fermenting, storing and transporting livestock and poultry manure to the soil in the cultivated land, it must be subjected to the metabolic expansion of mold many times. It produces air pollutants such as hydrogen sulfide, ammonia, and nitrogen, which is time-consuming and labor-intensive, and wastes energy in many links. Moreover, the organic matter in the soil has poor retention and cannot be maintained for a long time.
